# RD Sharma Solutions Class 12 Differentials Errors And Approximations

## RD Sharma Solutions Class 12 Chapter 14

Let $y=f(x)$ be a function of x, and let \Delta x be a small change in x and $\Delta y$  be the corresponding change in y. Then,

$\Delta y=dy/dx\, \Delta x$ approximately

dy/dx \Delta x is termed as differential of y and is denoted by $dy$

Some of the useful result on differentials

• If $f(x)$ is a constant function, then its differential is zero.
• If $y=cu$, then $dy=c\, du$, $c$ is a constant.
